Quick Answer

razer-synapse.exe is safe. It runs the Razer Synapse 3 software that configures lighting, macros, and device profiles for Razer peripherals.

What is razer-synapse.exe?

razer-synapse.exe is the main executable for the Razer Synapse 3 lighting and device-configuration suite. It coordinates connection to Razer devices, loads lighting profiles, stores per-device mappings, and handles cloud sync. Several subprocesses run to manage drivers, peripheral I/O, and telemetry, while the user interface remains responsive and ready to apply changes.

This modular approach isolates device drivers, lighting calculations, and cloud sync in separate processes, improving stability and security. The main client delegates I/O to specialized components while applying user profiles.

Quick Fact: Razer Synapse introduced per-device controller architecture to support complex lighting effects across dozens of devices.

Types of Razers Synapse Processes

Client/UI Process: Main window, user interface, and orchestration
Device Service: Per-device drivers and I/O handling
Lighting Engine: Real-time RGB/ARGB rendering for devices
Macro/Profile Service: Macros, keys, and programmable profiles
Cloud Sync Service: Syncs profiles and settings with Razer cloud
Telemetry/Updater: Usage telemetry and software update tasks

Is razer-synapse.exe Safe?

Yes, razer-synapse.exe is safe when it is the legitimate file from Razer downloaded from official sources (razers.com or via the Razer Central installer).

Is razer-synapse.exe a Virus or Malware?

The genuine razer-synapse.exe is not a virus. Malware may imitate names, so verify the file path and signature.

How to Tell if razer-synapse.exe is Legitimate or Malware

File Location:: Must be in C:\Program Files (x86)\Razer\Synapse3\ or C:\Program Files\Razer\Synapse3\. Any razer-synapse.exe elsewhere is suspicious.
Digital Signature:: Right-click razer-synapse.exe -> Properties -> Digital Signatures. Should show a valid signature from "Razer USA Ltd" or a logo of Razer Inc.
Resource Usage:: Normal usage is low to moderate CPU with occasional spikes during startup; memory usage varies with device count (roughly 100-400 MB). Persistent high usage when idle is suspicious.
Behavior:: Razer Synapse should launch when you start the system or when you manually open the app. Multiple background processes when the app is closed could indicate malware.

Red Flags: If razer-synapse.exe is located in unusual folders (like Temp, AppData, or System32), runs when Synapse isn't open, has no digital signature, or uses unexpected resources, scan your system. Watch for similarly-named files such as "razer-synapse8.exe" or "razer-synapsev3.exe".

Why Is razer-synapse.exe Running on My PC?

razer-synapse.exe runs to manage your Razer peripherals, load lighting profiles, and respond to hardware events. It may also wake to apply macro changes or cloud-synced settings.

Reasons it's running:

Active Synapse Use: You have Razers devices connected and configured; the client maintains device channels and profiles.
Background Device Sync: Synapse keeps lighting and key maps synced with the cloud and connected devices in real time.
Startup Program: Razer Synapse may be configured to launch at Windows startup to apply profiles automatically.
Macro/Profile Updates: New macros, lighting effects, or profiles can trigger the process to initialize or reconfigure modules.
Hardware Event Triggers: Connecting or changing devices (RGB keyboards, mice) triggers the device service to initialize or update state.

Can I Disable or Remove razer-synapse.exe?

Yes, you can disable razer-synapse.exe. It's safe to close Razer Synapse when not in use, and you can uninstall it if you prefer a different setup or lighting control.

How to Stop razer-synapse.exe

Exit the App: Close the Razer Synapse window or click the system tray icon and choose Exit
End Background Tasks: Open Task Manager, locate razer-synapse.exe, and End Task
Prevent Startup: Task Manager → Startup tab → Disable Razer Synapse
Disable Cloud Sync: Within Razer Synapse settings, turn off cloud sync and background services
